Police are appealing for information following the serious assault of a man at a convenience store in Liverpool last month.

A man entered the store on Macquarie Street and threatened staff with a knife about 5.30pm on Monday, June 30.

The manager was called to the store and asked the man to leave the premises.

While the armed man was walking out of the premises he grabbed the manager by the throat and pushed him to the ground before kicking and stomping on his head a number of times before fleeing the scene.

The 50-year-old man lost consciousness during the assault and was treated at the scene by paramedics for chest and facial injuries.

Liverpool police conducted searches of the area but were unable to locate the armed man.

Investigators have now released closed-circuit television images of a man who they believe may be able to assist with inquiries.

The man depicted in the images is described as being of Indian/Sub-continental appearance, 20-30 years old with a medium build, short dark hair, and wearing a black baseball cap, black jacket, white t-shirt, black jeans and black joggers.

Anyone who witnessed the assault or has information regarding the identity and whereabouts of the man in the CCTV images is asked to contact Liverpool Police.

Police are urging anyone with information about this incident to call Crime Stoppers on 1800 333 000 or use the online reporting page: https://www1.police.nsw.gov.au/.
